External use of internal buck regulator of STSPIN32G4

[FedericoHW]

Hello,

I want to ask a question about internal buck switching converter of STSPIN32G4.

We want to use its output voltage of 10V or 12V to supply an external potentiometer.

Is this converter indicated to use for power supply external devices requiring 10mA about?

 

Thank you in advance

Best Regards,

Well, as long as the thermal situation allows it (thermal shutdown), the step-down regulator can supply up to 200mA (data sheet, table 2). So your 10mA should not be a big problem if you use a proper heat sink.

Hope that helps?
